Who are the people that get so angry online? Why do so many of them choose to harass people, threaten people, and stretch the freedom of speech to its limits? More than a third of us participate in online debates, according to research done by Pew Research Centre.

Robert Jackson spends hours every day commenting online. Recently he wrote that Tony Blair should be hanged. “I stand by that,” he says. “I’d gladly put the rope around his neck. He’s a traitor to his people.”

Her visa only lasts for six months, and then she has to go back. And then we have to do the same thing all over again.”
